PostgreSQL provides various statistics which includes information about
tables, indexes, functions and other database objects and their usage.
Moreover, statistics has detailed information about connections, current
queries and database operations (INSERT/DELETE/UPDATE). But most of this
statistics are provided as permanently incremented counters. The
pgcenter provides convenient interface to this statistics and allow
viewing statistics changes in time interval, eg. per second. The
pgcenter provides fast access for database management task, such as
editing configuration files, reloading services, viewing log files and
canceling or terminating database backends (by pid or using state mask).
However if need execute some specific operations, pgcenter can start
psql session for this purposes.
